The Pantheon
Nearly 2,000 years old and still the best-preserved ancient building on earth, the Pantheon stops first-time visitors dead in their tracks. Step inside and tilt your head back: that 9-metre oculus in the coffered concrete ceiling is the only light source, and it has been open to the sky since 125 AD.
Why It Still Astonishes
The dome's diameter (43.3 m) exactly equals its interior height — a geometric perfection that Renaissance architects spent centuries trying to decode. Michelangelo reportedly said angels, not men, must have built it.
The building served as a church from 609 AD, which is precisely why it survived while every other Roman temple crumbled. You can pay your respects at the tombs of Raphael and two Italian kings tucked into the niched walls.
Making the Most of Your Visit
Arrive right when the doors open at 9 am to beat the queues and catch the morning light shaft from the oculus sweeping across the marble floor — one of Rome's most cinematic moments.
Book timed-entry tickets online in advance; since 2023 entry costs €5 and free-entry days are gone. The piazza outside, Piazza della Rotonda, is ringed with café terraces — grab a post-visit espresso at Caffè della Pace just two minutes' walk away.
